If true, tells the focus traversal policy to skip over this node for
purposes of the traversal algorithm.
getter/setter pairinherited
-
traversalChildren
→ Iterable<FocusNode>
-

FocusTraversalPolicy.
no setterinherited
-
traversalDescendants
→ Iterable<FocusNode>

the canRequestFocus flag set.
no setterinherited
Methods
-
addListener(VoidCallback listener)
→ void
-
Register a closure to be called when the object changes.
inherited
-
attach(BuildContext? context, {FocusOnKeyEventCallback? onKeyEvent, FocusOnKeyCallback? onKey})
→ FocusAttachment
-
Called by the host StatefulWidget to attach a FocusNode to the
widget tree.
inherited
-
consumeKeyboardToken()
→ bool
-
Removes the keyboard token from this focus node if it has one.
override
-
debugDescribeChildren()
→ List<DiagnosticsNode>
-
Returns a list of
DiagnosticsNode objects describing this node's
children.
inherited
-
debugFillProperties(DiagnosticPropertiesBuilder properties)
→ void
-
Add additional properties associated with the node.
inherited
-
dispose()
→ void
-
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
focusInDirection(TraversalDirection direction)
→ bool
-
Request to move the focus to the nearest focus node in the given
direction, by calling the FocusTraversalPolicy.inDirection method.
inherited
-
nextFocus()
→ bool
-
Request to move the focus to the next focus node, by calling the
FocusTraversalPolicy.next method.
inherited
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners()
→ void
-
Call all the registered listeners.
inherited
-
previousFocus()
→ bool
-
Request to move the focus to the previous focus node, by calling the
FocusTraversalPolicy.previous method.
inherited
-
removeListener(VoidCallback listener)
→ void
-
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
requestFocus([FocusNode? node])
→ void
-
Requests the primary focus for this node, or for a supplied
node, which
will also give focus to its ancestors.
inherited
-
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style})
→ DiagnosticsNode
-
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString({DiagnosticLevel minLevel = DiagnosticLevel.info})
→ String
-
A string representation of this object.
inherited
-
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug})
→ String
-
Returns a string representation of this node and its descendants.
inherited
-
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug})
→ String
-
Returns a one-line detailed description of the object.
inherited
-
toStringShort()
→ String
-
A brief description of this object, usually just the runtimeType and the
hashCode.
inherited
-
unfocus({UnfocusDisposition disposition = UnfocusDisposition.scope})
→ void
-
Removes the focus on this node by moving the primary focus to another node.
